Solve each equation using the quadratic formula. Find the exact solution, then approximate the solution to the nearest hundredth
Mariana [72]

Answer:

n_1=2.72\\n_2=0.61


Step-by-step explanation:

 To solve this problem you  must apply the proccedure shown below:

1. You have that the quadratic formula is:

x=\frac{-b+/-\sqrt{b^{2}-4ac}}{2a}

2. To solve the quadratic equation you must substitute the values. So, you have that:

a=3\\b=-10\\c=5

Then you have:

 x=\frac{-(-10)+/-\sqrt{(-10)^{2}-4(3)(5)}}{2(3)}

3. Therefore, you obtain the following result:

x_1=2.72\\x_2=0.61
